Millets and pulses are better suited for:

The correct answer is: a) Fertile coastal plains.

Millets and pulses are better suited for fertile coastal plains because they are drought-tolerant and can grow in poor soils. They are also relatively low-maintenance crops, which makes them a good choice for farmers in developing countries.

Red soils of the interior are not as well-suited for millets and pulses because they are more prone to drought and erosion. Mountainous regions are also not ideal for these crops because they are often too cold and dry. Saline soils are also not suitable for millets and pulses because they contain high levels of salt, which can damage the plants.

Here is a more detailed explanation of each option:

• Fertile coastal plains are ideal for millets and pulses because they are well-drained and have a high level of organic matter. These conditions are necessary for the growth of these crops.
• Red soils of the interior are not as well-suited for millets and pulses because they are more prone to drought and erosion. Red soils are also often acidic, which can damage the plants.
• Mountainous regions are also not ideal for these crops because they are often too cold and dry. The high altitude and low temperatures in mountainous regions can make it difficult for millets and pulses to grow.
• Saline soils are also not suitable for millets and pulses because they contain high levels of salt, which can damage the plants. The high salt content in saline soils can make it difficult for the plants to absorb water and nutrients.
